How can I find my settings and replays?

Slap City stores its settings and replays in a folder located at:

C:\Users\YOURNAME\AppData\LocalLow\Ludosity\Slap City

where C is the drive where Windows is installed and YOURNAME is the user name you´re using to log into windows. You might need to turn on Show Hidden Folders to see AppData, but typing the address will always work.

Fun fact, the folder name "Users" is localized into whatever language you´ve set Windows to, but the English word will also always works as that's its "real" folder name behind the scenes.
